Problem 1

Answer: B) -15

---------------------------

Step-by-step explanation:

Draw out a number line with -7 on it. Stuff to the left of this value are smaller than -7. Stuff to the left would be -8, -9, ... and -15 is part of that list.

So -15 is smaller than -7.

================================================

Problem 2

Answer: Choice A) closed circle at 2 and shading to the right

--------------------------

Step-by-step explanation:

Let's solve for h


-5h+3 \le -7\\\\-5h \le -7-3\\\\-5h \le -10\\\\h \ge (-10)/(-5)\\\\h \ge 2\\\\

The inequality sign flips because we divided both sides by a negative value.

The solution set is the set of h values such that h = 2 or h > 2. In short, h can be 2 or larger.

Visually this will be a graph with a closed circle at 2 and shading to the right. The closed circle tells the reader "include the endpoint". This describes graph A.
